Answer:
Step-by-step explanation:
the formula for calculating the perimeter of a circle (the circumference C) is:
2π * r
And the area is:
π * r²
r is the radius.
Radius is the half of the diameter. The diameter here is equal to two square. One square is 5 of side.
The diameter is 10 and the radius is 5
C = 2 * 3.14 * 5 = 31.4
A = 3.14 * 5² = 3.14 * 25 = 78.5
It is the same for the other circle
